UNITED s'rA-TEs PATENT G AsrHALT-SPREADING MACHINE.

Application filed October 15, 1923.

To all w/wm it may ooncern:

Be it known that I, ROBERT E. GARRETT, a resident of Nashville, in the county of Davidson and State of Tennessee, a citizen of the United States, have invented certain new and useful Improvements in Asphalt- Spreading Machines, of which the following is a specification.

My invention relates to improvements in asphalt-spreading machines, particularly adapted for surfacing road beds with asphalt or like material in the process of road building, although the machine may be used for any purpose where it would perform its functions in a proper manner.

The main object of my invention is the provision of a machine which can be easily drawn over the ground to evenly deposit or spread the asphalt or other material upon the road.

Another object of my invention is the provision of a machine of the Character and for the purpose stated which will be composed of very few parts to insure simplicity, durability and cheapness of construction and which will be thoroughly eflicient and practical in every respect.

With these objects in view my invention consists of an asphalt spreading machine embodying novel features of construction and combination of parts, substantially as described and claimed and as shown in the accompanying drawing, in which Figure 1 represents a side view of an asphalt spreading machine constructed in accordance with and embodying my invention, the view being partly broken away to show details of construction.

Figure 2 represents a top plan view of the machine, and

Figure 8 represents a detail view.

Figure 4 represents a plan view o-f a modification The machine is of the simplest possible construction and comprises a bodyV A, of rectangular form and of the desired capacity, having the forward inclinecl end B, and the rear open straight end G, which is formed with guides D, for the door or gate E, such being adjustable to regulate the amount of delivery of material by means of the openings F and pin G, said body being mounted on front and rear axles H, carrying the ground wheels J.

The body is drawn over the ground by any suitable means and the front axle carries Serial No. 668,653.

a pair of gear wheels K, which mesh with the pair of gear wheels L, on 'the ends of the shaft M, said shaft thus being rotatedy from the gear Wheels K, and imparting' travel to the endless apron N, which is guided by the front and rear Wheels O, and carries the cross pieces` P, which, serve to engage lthe asphalt or other material in the travel of the endless apron and deposit the same in an even manner at the rear discharge end Q, of said body, the amount of delivery of material being regulated by the adjustable gate.

The advantages of my machine will be readily understood and appreciated by all persons skilled in road building and it will be apparent that the machine will insure the delivery of the material in an even manner and in the exact amount desired and the simplicity, durabilit-y and cheapness of the machine will recommend it as a desirable and practical improvement.

In the modification of my invention shown in Figure 4, the body or scoop is provided with parallel division strips R, removably mounted in guides S, this construction allowing a 'determined 'amount' or' an even strip of material to be delivered, which is of great advantage and importance.

It will be noted that the open end of the body is vertically disposed and is provided with guides in which fits the gate, w'hich can be adjusted to regulate the amount of material discharged, as said gate acts in conjunction with the closed flexible apron or conveyor and the seats thereon, which is a most important feature of my invention.4

In my machine there is a coaction or combination between the adjust-able end gate, the endless belt or carrier, and the division walls in the body, as the gate acts to regulate the amount of discharge of concrete or asphalt and smooths it off to insure an even distribution and the division walls with the adjustable gate allows various widths of concrete or asphalt paving to be effected by discharging different widths of the material.

I claim: t i

An asphalt spreading machine co-nsisting of the body having an inclined closed forward end and an open Vertical rear end, strips in said body for dividing it into compartments for receiving mate-rial, Vertical guides in said open end, a g'ate adjustable in said guides to regulate amount of discharge from said body, a pair of shafts mounted in the front and real' of the body,

FFlcE.

the front shaft havngextended ends, Wheels carried by said sha'fts, an endless earrer closed to provide an apr'on travellng upon said Wheels and formng o movable closed 5 bottom for the body, cross-strps on said earrer, formng pockets to' receive and conyey the material, gear Wheels` on the extended ends of the front shaft, front and rear axles carryng Wheels and gear Wheels on the front aXle meshng With the gear Wheel on the 10 front shaft for' rnpartng movement to said endless earrer aeothemaehne travels over the ground.

In testimony Whereof I hereunto affix my signature.

ROBERT E. GARRETT.
